영상의학과 내원한 보호자의 방사선 위해성에 관한 인식 분석

Abstract

The purpose of this study is to suggest the basic data that were necessary for exposure management in radiological examination based on investigation of knowledge about radiation, awareness of radiation exposure and awareness of radiation-related policies among guardians who visited the radiology department, which ultimately provided help to manage radiation safety in a more efficient way and to establish measures for such management. In this study, survey was conducted for guardians who visited the radiology department of J hospital in Daegu city of South Korea in the period from January 14 to March 27, 2013. The survey resulted in the conclusions as follows. Level of knowledge about natural radiation depending on level of education showed the difference with statistical significance (p=0.000). The score was 4.06 points for graduates of graduate school, 3.62 points for graduates of university, and 3.54 points for graduates of college. The higher level of knowledge about radiation resulted in the lower level of anxiety while the higher level of anxiety in radiological examination led to the higher level of fear of radiation risk. Therefore, when radiological examination is conducted, it is required for radiologists to provide patients and their guardians with education by using materials such as guidebook on examination and to clearly explain purpose of examination and matters that require attention in examination with a view to helping the patients and their guardians stay away from fear and anxiety. It is believed that management of radiation safety should not be neglected and that efforts should be made to reduce radiation exposure as much as possible.
